CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a national stage application under 35 U.S.C. §371 of PCT application PCT/US2015/032069, filed on May 21, 2015, which claims the benefit of U.S. Provisional Patent Application No. 62/001,188, filed May 21, 2014, the entire contents of each of which is incorporated herein by this specific reference.

FIELD OF THE INVENTION

The present invention relates to imidazole derivatives, processes for preparing them, pharmaceutical compositions containing them, and their use as pharmaceuticals as modulators of the N-formyl peptide receptor (FPR), such as the N-formyl peptide receptor 2 (FPR2). The invention relates specifically to the use of these compounds and their pharmaceutical compositions to treat disorders associated with FPR modulation, such as FPR2 modulation.

BACKGROUND OF THE INVENTION

The FPR family belongs to the seven transmembrane domain G-protein-coupled receptor (GPCR) family. This family includes three members in humans. One member of this family, FPR2 (also known as FPRL-1 or ALXA4), is expressed predominantly on inflammatory cells, such as monocytes and neutrophils, as well as on T cells, and has been shown to play a critical role in leukocyte trafficking during inflammation and human pathology (See Chiang N, Serhan C N, Dahlen, S, Drazen J M, Hay D W P, Rovati E, Shimizu T, Yokomizo T, Brink, C. The lipoxin receptor ALX: Potent ligand-specific and stereoselective actions in vivo. Pharmacological Reviews 2006; 58: 463-519).

FPR2 is an exceptionally promiscuous receptor that responds to a menagerie of structurally diverse exogenous and endogenous ligands, including serum amyloid A (SAA), chemokine variant sCKβ8-1, the neuroprotective peptide humanin, anti-inflammatory eicosanoid lipoxin A4 (LXA4) and glucocorticoid-modulated protein annexin A1 (Chiang N, Serhan C N, Dahlen, S, Drazen J M, Hay D W P, Rovati E, Shimizu T, Yokomizo T, Brink, C. The lipoxin receptor ALX: Potent ligand-specific and stereoselective actions in vivo. Pharmacological Reviews 2006; 58: 463-519).

FPR2 transduces anti-inflammatory effects of arachidonic acid derived LXA4 in many systems, and has been shown to play a key role in the resolution of inflammation (Dufton N, Perretti M. Therapeutic anti-inflammatory potential of formyl peptide receptor agonists. Pharmacology & Therapeutics 2010; 127: 175-188).

FPR2 knockout mice show exaggerated inflammation in disease conditions, as expected from the biological role of the receptor (See Dufton N, Hannon R, Brancaleone V, Dalli J, Patel H B, Gray M, D'Aquisto F, Buckingham J C, Perretti M, Flower R J. Anti-inflammatory role of the murine formyl-peptide receptor 2: Ligand-specific effects on leukocyte responses and experimental inflammation. Journal of Immunology 2010; 184: 2611-2619.

FASEB 2012; 26: 1-13).

Activation of FPR2 by LXA4 or its analogs and by annexin I protein has been shown to result in anti-inflammatory activity by promoting active resolution of inflammation, which involves inhibition of polymorphonuclear neutrophils (PMNs) and eosinophils migration, and also stimulating monocyte migration, enabling clearance of apoptotic cells from the site of inflammation in a nonphlogistic manner (See Gavins F N E, Hughes E L, Buss N A P S, Holloway P M, Getting S J, Buckingham J C. Leukocyte recruitment in the brain in sepsis: involvement of the annexin1 FPR2/ALX anti-inflammatory system. FASEB 2012; 26: 1-13, Maderna P, Cottell D C, Toivonen T, Dufton N, Dalli J, Perretti M, Godson C. FPR2/ALX receptor expression and internalization are critical for lipoxin A4 and annexin-derived peptide-stimulated phagocytosis. FASEB 2010; 24: 4240-4249).

In addition, FPR2 has been shown to inhibit natural killer (NK) cytotoxicity and promote activation of T cells, which further contributes to down regulation of tissue damaging inflammatory signals.

FPR2 interaction with LXA4 and annexin has been shown to be beneficial in experimental models of dermal inflammation, angiogenesis, epithelial migration, edema, alopecia, ischemia reperfusion and ocular inflammation, such as endotoxin-induced uveitis and corneal wound healing (See Reville K, Cream J K, Vivers S, Dransfield I, Godson C.

Pharmaceutical utility of LXA4 and its analogs is hampered by inherent physicochemical properties of the natural poly-olefinic natural product. Therefore, small molecule anti-inflammatory agonists of FPR2 would have a wide variety of therapeutic benefits in inflammatory disorders, including inflammatory disorders of the eye. Targeting FPR2 selectively would also have benefits of reduced side effects as compared to more broadly acting anti-inflammatories, such as steroids or NSAIDs, which have significant side effects of elevated 10P and delays in wound healing in the eye. FPR2 is also expressed in ocular tissues in the cornea and in the posterior of eye, in addition to the inflammatory cells that migrate into the ocular tissues.

Targeting FPR2 selectively would also have benefits in skin wound healing, given its potent anti-inflammatory and pro-epithelial repair role. In addition, some skin diseases have been shown to have an abnormal expression of LL37, a pro-inflammatory cathelicidin which has been shown to be a natural ligand of FPR2. In the chronic inflammatory disease rosacea, LL37 is highly expressed and is believed to play a key role in the pathogenesis (Yamasaki K, Di Nardo A, Bardan A, Murakami M, Ohtake T, Coda A, Dorschner R A, Bonnart C, Descargues P, Hovnanian A, Morhenn V B, Gallo R L. Increased serine protease activity and cathelicidin promotes skin inflammation in rosacea. Nature Medicine. 2007; 13:975-80).

FPR2 thus represents an important novel pro-resolutionary molecular target for the development of new therapeutic agents in diseases or conditions involving excessive inflammatory responses.

Some of the compounds of Formula I and some of their intermediates may contain one or more asymmetric centers in their structure; each asymmetric center may be present in an R or S configuration, said R and S notation corresponding to the rules described in Pure and Applied Chemistry (1976), 45, 11-13. As such, the compounds may exist in enantiomeric as well as in diastereomeric forms. Unless it is specifically noted otherwise, the scope of the present invention includes all enantiomers, diastereomers and mixtures thereof, including racemic mixtures.

As will be evident to those skilled in the art, individual diastereoisomeric forms can be obtained by separation of mixtures thereof in a conventional manner. For example, chromatographic separation may be employed; chiral chromatography may be performed to separate individual enantiomers.

The present invention includes all pharmaceutically acceptable isotopically enriched compounds. Any compound of the invention may contain one or more isotopic atoms enriched or different than the natural ratio, such as deuterium ²H (or D) in place of hydrogen ¹H (or H), or use of ¹³C enriched material in place of ¹²C and the like. Similar substitutions can be employed for N, O, S and P. The use of isotopes may assist in analytical as well as therapeutic aspects of the invention. For example, use of deuterium may increase the in vivo half-life by altering the metabolism (rate) of the compounds of the invention. These compounds can be prepared in accord with the preparations described by use of isotopically enriched reagents.

Buffers, preservatives, antioxidants, and the like can be incorporated as required.

Pharmaceutical compositions containing invention compounds may be in a form suitable for topical use, for example, as oily suspensions, as solutions or suspensions in aqueous liquids or nonaqueous liquids, or as oil-in-water or water-in-oil liquid emulsions. Pharmaceutical compositions may be prepared by combining a therapeutically effective amount of at least one compound according to the present invention, or a pharmaceutically acceptable salt thereof, as an active ingredient with conventional ophthalmically acceptable pharmaceutical excipients and by preparation of unit dosage suitable for topical ocular use. The therapeutically efficient amount typically is between about 0.001 and about 5% (w/v), preferably about 0.001 to about 2.0% (w/v) in liquid formulations.

For ophthalmic application, preferably solutions are prepared using a physiological saline solution as a major vehicle. The pH of such ophthalmic solutions should preferably be maintained between 4.5 and 8.0 with an appropriate buffer system, a neutral pH being preferred but not essential. The formulations may also contain conventional pharmaceutically acceptable preservatives, stabilizers and surfactants. Preferred preservatives that may be used in the pharmaceutical compositions of the present invention include, but are not limited to, benzalkonium chloride, chlorobutanol, thimerosal, phenylmercuric acetate and phenylmercuric nitrate.

The ingredients are usually used in the following amounts:

Ingredient Amount (% w/v) active ingredient about 0.001-5 preservative   0-0.10 vehicle 0-40 tonicity adjustor 0-10 buffer 0.01-10   pH adjustor q.s. pH 4.5-7.8 antioxidant as needed surfactant as needed purified water to make 100%

The actual dose of the active compounds of the present invention depends on the specific compound, and on the condition to be treated; the selection of the appropriate dose is well within the knowledge of the skilled artisan.

The ophthalmic formulations of the present invention are conveniently packaged in forms suitable for metered application, such as in containers equipped with a dropper, to facilitate application to the eye. Containers suitable for dropwise application are usually made of suitable inert, non-toxic plastic material, and generally contain between about 0.5 and about 15 ml solution. One package may contain one or more unit doses. Preservative-free solutions are often formulated in non-resalable containers containing up to about ten, preferably up to about five units doses, where a typical unit dose is from one to about 8 drops, preferably one to about 3 drops. The volume of one drop usually is about 20-35 microliters.

The compounds of the invention may also be administered in the form of suppositories for rectal administration of the drug. These compositions may be prepared by mixing the invention compounds with a suitable non-irritating excipient, such as cocoa butter, synthetic glyceride esters of polyethylene glycols, which are solid at ordinary temperatures, but liquefy and/or dissolve in the rectal cavity to release the drug.

Since individual subjects may present a wide variation in severity of symptoms and each drug has its unique therapeutic characteristics, the precise mode of administration and dosage employed for each subject is left to the discretion of the practitioner.

The present invention concerns also processes for preparing the compounds of Formula I. The compounds of Formula I according to the invention can be prepared analogously to conventional methods as understood by the person skilled in the art of synthetic organic chemistry. Synthetic Scheme 1, set forth below, illustrates how the compounds according to the invention can be made.

-   Scheme 1. Methods of preparing compounds of the invention. The     variable groups are as defined for Formula I, unless specifically     indicated otherwise. Compound E is the compound of Formula 1,     wherein m is 0 or 1, n is 1, 2, 3, 4, 5, 6, 7 or 8, and R⁸ is not     OH). Compound F is the compound of Formula I, wherein m is 1, n is     1, 2, 3, 4, 5, 6, 7 or 8, and R⁸ is OH. In Intermediate D, m is 0 or     1, n is 1, 2, 3, 4, 5, 6, 7 or 8, and R⁸ is not OH.

Compounds of Formula I can be prepared as depicted in Scheme 1. In general, Intermediate A is reacted with a substituted phenylisocyanate (Intermediate B) to produce Compound C (Scheme 1a). Compound C can be further modified to provide Compound E or F (Schemes 1b and 1c). For example, Compound C is reacted with Intermediate D to yield Compound E. When Compound E is an imidazole ester, the ester may be hydrolyzed to provide the corresponding carboxylic acid, Compound F.
